To all whom it may concern:

tie it known that I, THORWALD C. S'rnnn, a citizen of the United States, residingat Jacksonville, in the county of Dnval and State of Floridayhave invented new and useful improvements in Shears, of which the following is a specification.

My present invention has reference to that class ofshears used by metal workers and known as snips.

The object of the invention is to produce a cutting device of this character in whlch the blades can be arranged at varying angles with respect to the handles therefor, so that sheets of metal may be easily cut at angles or circles which are impossible with the employment of. ordinary snips.

A further object is to produce a pair of snips in which the cutting blades are both removable and adjustable angularly with respect to the handles of the snipe, and whereby the blades cannot only be conveniently positioned to make difficult cuts that can hardly be made by the ordinary snips, but also wherein an injured or broken blade can be easily replaced by a new one.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings 2- Figure 1 is a plan view of a pair of snips constructed in accordance with this invention, the blades being arranged in longitudinal alinement with the handles thereof.

Fig. 2 is a similar view but showing the blades arranged at an angle with respect to the handles.

Fig. 8 is an edge view with parts broken away and parts in section, the dotted lines illustrate curved blades which may be em ployed.

My improved snips are broadly indicated in the drawings by the numeral 1. The handles for the snips are indicated by the numerals 2 and 3 respectively. These handles are rounded toward their body portions which are indicated by the numerals 4 and 5 respectively. The body portions 1 and 5 are arranged in lapping relation in the usual manner, and the said body portions are pivotally connectedby a pivot pin 6. The pin has one end headed and its other end Specification of Letters Patent.

threaded, and on the threaded end there is screwed a nut 7 that contacts with the outer face of the body portion 5 of the handle 3. reference to the drawings, it will be seen that the ends of the handles, which I have referred to as the body portions thereof are one of a greater length than the other, the body 5 terminating in. a round head 8 provided with peripheral teeth 9, while the body 1, at the portion thereof extending be yond the head 8 has its inner face depressed and the outer. surface provided by the depression formed with radial teeth 10. The

portion of the body on which the teeth 10 are formed is in the nature of a head, and is designated by the numeral 11. The head 11 has a central opening therethrough for the reception of a pivot pin of a peculiar construction. numeral 12, and has both of its ends threaded but is, approximately centrally, formed with a continuous flange 13 whose outer and widened face is straight, as at 1a, and its inner face flared inwardly toward the pin,

The pin is indicated by the as at 15. The flared portion 15 provides a conical shoulder which is received in a conical opening 16 in a blade 17. The blade 17 has its inner end rounded to provide what may be termed a head portion 18, the said head being depressed from its outer face and its said outer face formed with radial ribs 19 that are designed to be received between the radial ribs 10 in the head 11. The blade 17 while adjustable on the pivot pin 12, and consequently susceptible to lateral adjust ment with respect to the handle 2, is de signed to be fixed at such adjustments, and

will therefore be referred to as the fixed rib. The swinging blade is indicated by the numeral 18 and has its inner end provided with a rounded portion in the nature of a head 19. The head has peripheral teeth 20 and is centrally provided with an opening for the reception of the end portion 21 of the pivot pin 13. The threaded ends of the pivot pin are engaged by suitable nuts 22 respectively, and the teeth 20 are in mesh with the teeth 9 on the head of the handle 2.

By removing the nut 22 that contacts with the pivot or articulated jaw 18, both of the cutting jaws may be removed from the handles, or at least partly removed therefrom and arranged at a desired angle with respect to said handles. The nuts are again screwed on the threaded ends of the pivot pin, and the handles are operated in the ordinary manner for swinging the articulated jaw 18 toward or away from the fixed jaw 17. With a snip constructed as above described, it will be noted that a metal worker can make cuts in a sheet of metal which would be found difficult, if not impossible, by the employment of the ordinary snips. The blades 1'7 and 18 being removable may be easily sharpened, or if broken or otherwise seriously damaged, the said blades may be easily replaced and it is thought that further detailed description will not be necessary.

Having described the invention, I claim l. A sheet metal workers snips, as herein described, comprising two handle members having lapping body portions which are pivotally connected, the body of one of the handles being of a greater length than the other, and the last mentioned body having its inner face depressed, rounded in plan, formed with radial teeth, a jaw having its outer face at its inner end depressed and formed with radial teeth engaging the first mentioned teeth, the body of the second jaw having a rounded end provided with peripheral teeth, a second jaw having its inner end rounded and provided with teeth to engage between the first mentioned teeth, a

pivot passing through both of the jaws and through the end of the body of the first mentioned handle, said pivot having a flared shoulder received in a flared opening in the first mentioned jaw, the pivot having both of its ends threaded, and nuts screwed on said ends and contacting with the outer fares of both of the jaws.

2, A snips comprising two handles which are )ivotally connected, one of said handles being 0-: a greater length than the other and having a cutting blade beyond its pivot, the shorter handle having its pivot end rounded and toothed, a second cutting blade pivot-ally connected to the first mentioned cutting blade and having its inner end round d and toothed and its said toothed end engaging the teeth of the second mentioned handle.

In testimony whereof I afiix my signature.
